| The concept of Business Intelligence (BI) was first proposed in1996. At that time, business intelligence is defined as a class of technology or application for the purposes of helping business decision, which is composed of data warehousing, query reporting, data analysis, data mining, data backup and recovery and other components. Business intelligence can assist in business decision-making for either operating layer or tactical and strategic layer. In order to transform data into knowledge, you need to use the data warehouse, tools of online analytical processing (OLAP) and techniques of data mining. Modern enterprise use BI management platform in integrating the currency data effectively to provide. decisions f a stand accurately, which can help companies to make business decisions. Therefore, from a technical perspective, Business Intelligence is the synthetically application of data warehousing, OLAP and data mining.Recently, the hospital’s information technology is developing fast. It has more and more applications. Its functional coverage gets smaller, and it generates the increasing amount of data. However, the management in hospital only remains in the stage of data reporting, which cannot maximize the effect of the data warehouse created in application. From clinical management, the capa BI lity of data analysis needs stronger. Thus, BI management platform in enterprise used in the hospital is very necessary. The core of BI management platform is data mining techniques, in other words, the data warehouse and data mining technology builds up the BI management platform.Hospital can use this data platform technology to find the intrinsic link in the vast amounts of data, which can find the hidden information between potential diagnostic data. By these relationships, it can improve diagnostic accuracy in hospital, enhance the integrated utilization of hospital resources and improve patient satisfaction.This paper mainly introduces the related concept and principles of BI theories, and the applications, effects of hospital informational construction. The first chapter introduces the background of BI application in hospital management; the second chapter introduces the HIS, data mining and other related concepts; the third Chapter:summary of BI project mainly sets on the background of the project, and main functions of the objectives and achievement. Chapter four shows BI design solutions in the hospital informational construction; Chapter five is Summary and Prospect. |
